Non-Directional  Beacon  (NDB)  Photo  Gallery 
By  Stephen  P.  McGreevy  -  N6NKS 

Updated  07  March  2019:  Many  print-images  re-scanned  and  vastly  improved;  All  images  now  auto-load  inline;  more  NDBs  from  the 
1980s  and  also  four  MWBCB  transmitter-site-photos  have  been  added  (former  1510  KTIM-San  Rafael,  CA;  former  1610  TIS  Point 
Reyes  National  Seashore-North  Beach/Cuyamaca  SP  Calif.);  Oregon  and  California  OTH-b  HF  radar  installations  -  1990;  and 

more...

The  former  25-watt,  375  kHz  "  EMC"  -  Winnemucca,  Nevada  (off-air  since  2002).  Photo  by  Stephen  P.  McGreevy,  June  1987.  Winnemucca  Mountain  is  in  the 

distant  background. 

Non-directional  beacon  (NDB)  photography:  The  following  is  a  gallery  of  non-directional  beacon  (NDB)  photos  taken  during  several  road-trips  between 
May  1984  and  December  2008,  mainly  of  NDB's  in  the  West,  Intermountain  regions,  and  High  Plains/Prarie  regions  of  Canada  and  the  United  States.  There 
are  also  photos  of  other  longwave  installations,  too.  Probably  over  2/3rds  of  the  U.S.  NDB's  pictured  here  are  now  off-the-air,  so  these  photos  can  be 
considered  historical,  especially  for  DXers  who  have  logged  them  in  the  past  when  NDB-band-density  was  vastly-higher,  pre-GPS  implementation.

Map  of  US  DGPS  data-stations  by  frequency  in  kHz  and  location  (generally  uninteresting  FSK  at  100  or  200  baud  unless  you're  into  decoding  these  things, 
but  they  are/were  useful  for  signal-propagation  observations).  Many/most  are  off-air  late  2017  now  (all  but  the  BLUE-marked  USCG  DGPS  beacons  are 
off-air  in  2018,  now  freeing  up  many  NDBs  into  audibility  again!  Example  -  the  lovely  305  RO-NM/ONO-OR  Mixture  is  in  the  clear  now  -  Bakersfield's  305

355  RK  “Reykjavik1'  (Seltjamarnes)  Iceland  -  flat-top — and  former  verticaf  lattice  mast  - 10  December  2016  -  SPMcGreevy 


355  RK  Reykjavik,  Iceland  is  located  at  a  golf  course  on  the  tip  of  the  Seltjamarnes  Peninsula  in  Seltjamarnes,  Iceland,  a  suburb  of  Reykjavik  to  the  west  of  the 


downtown  CBD.  This  beacon  employs  a  two-guy-cable-supported  "T"  antenna  (Marconi  type)  consisting  of  a  single  cable  up-lead  and  flat-top  section.  Photo  taken 
by  Stephen  P.  McGreevy  09  December  2016  on  a  long  walk  and  during  a  12-day  natural  ELF-VLF  research  trip  and  a  FW/MW  DXpedition,  also.  RK  is  1020  Hz 
ident-tone  USB  only  (at  the  time  of  my  visit),  with  a  USA-style  ident  (no  DAID).  I  was  staying  in  a  private  apt.  10  km  from  this  beacon,  and  on  this  fine,  mild  day,  I 
walked  to  the  Seltjamarnes  Nature  Preserve  and  golf  course  in  Seltjamarnes,  Iceland.  As  I  loved  the  long  nights  replete  with  full-moonlight  and  loads  of  pretty 
Christmas  Fights,  and  I  saw  three  nights  of  level  2-3  aurora...  as  such,  I  was  extremely  pleased  and  hugely  enjoyed  my  visit  and  consulting-time  there.  The  first 
overseas  NDB  I  have  visited.  Initially,  I  heard  it  on  an  EFF  rx.  as  it  was  nearby  my  listening  spot.  Curious,  the  next  day  I  walked  to  this  beacon.  Next  to  it  to  the  east 
about  100-meters  away  is  a  vertical,  self-supported  lattice-mast  near-identical  to  320  YQF  Alberta,  Canada  and  254  SPK  Nevada  but  also  included  an  elevated- 
counterpoise  very  similar  to  320  HTN  (pics  below,  and  the  former  RK-mast  is  very  visible  on  Google  Earth/ Apple  Maps).  That  was  the  former  NDB  for  RYK 
(airport),  now  this  355  kHz  'RK'  unit  and  antenna  seen  at  the  golf  course.  Parking  is  just  100m  away,  and  this  is  an  easy  NDB  to  visit  and  is  in  a  lovely  coastal 
peninsular  location!

368  SX  Cranbrook  (Skookumchuck),  British  Columbia.  Tall  vertical  mast  antenna.  Beautiful  Autumn  foilage  next  to  the  beacon,  with  the  a  bit  of  the  Canadian  Rocky 
Mountains  visible  in  the  background.  Gail  and  I  spent  many  hours  trying  to  find  this  beacon!  High-power  and  located  well  away  from  the  main  Highway  93.  A  strong 
signal  in  California  but  often  battling  it  out  with  stronger  ZP  Sandspit,  B.C.  -  (both  were  1020  Hz  USB  pitch  modulation  when  I  wrote  this  in  1999,  now  SX  and  ZP 
are  400  Hz  pitch  modulation  as  of  12/05  -  monitor  368.4  kHz).  S.  McGreevy,  photo  taken  September  1993.  368_sx.jpg,  62,466  bytes.

Dafoe,  Saskatchewan.  Medium-height,  guyed  antenna  mast  (mimicking  a  small  mediumwave  BCB  station  operating  around  1600  kHz).  Photographed  near  sunset  as 
we  drove  right  by  it,  I  didn't  immediately  recognize  it  as  an  NDB ,  and  we  kept  on  driving  for  a  few  km  before  I  thought  to  check  the  longwave  portable  to  see  if  was 
an  NDB  -  sure  enough,  it  was  (!),  so  we  drove  back  to  take  pictures.  VX  is  located  far  from  any  airport,  etc.,  in  a  field  with  nothing  else  around.  While  we  visited  this

(usually  25-watt)  Canadian  number/letter  ident  beacon  usually  found  at  small  airports  (see  328  5J  photo  just  below).  I  photographed  this  one  from  afar,  through 
binoculars,  from  the  entry  road  to  the  airport,  being  on  my  way  south  on  Hwy  37  with  the  goal  of  Waterton  Park  in  southen  Alberta  at  the  end  of  the  day  (and  it  was 
threatening  to  rain).  S.  McGreevy,  June  1996.  5E_353.jpg  28,855  bytes.  (SINCE  THIS  PHOTO  WAS  TAKEN  5E  CHANGED  IDENTS  TO  "5F")

I  328  -  5J,  Coronation,  Alberta.  A  good  close-up  of  another  small, 
privately-owned  number/letter  beacon.  Metal  lattice  mast  and  self-supporting  6-spoke  umbrella  top-hat  with  wire  skirt  and  two  red  marker  lights.  Occasionally  heard 
in  California,  weakly,  when  conditions  are  good  (monitor  328.4  kHz  in  narrowband  CW/SSB  mode).  S.  McGreevy,  September  1993.  5J_328.jpg  36,049  bytes.

224  DN  Dauphin,  Manitoba,  Canada  -  September  1993  -  SPMcGreevy 


224  DN  -  Dauphin, 


Manitoba.  This  beacon  is  a  fine  example  of  a  Canadian  NDB  employing  a  medium-height  lattice  antenna  mast  and  drooping  wire-capacitance  tophat/umbrella  (a 
mini- version  of  former  Omega-D  North  Dakota  and  many  Loran-C  installations!).  This  (400  Hz  USB  ident  modulation  pitch)  beacon  was  spied  right  along  the 
Highway  south  of  Dauphin  -  we  were  not  DFing  it.  I've  heard  this  one  in  California  regularly  when  conditions  to  Canada  are  good  (monitor  224.4  kHz  in  narrowband 
CW/SSB  mode).  S.  McGreevy,  September  1993.  DN_224.jpg  32,757  bytes. 


307  MS  -  Warming,  Alberta  -  SPMcGreeiry 


307  M5  -  Manning,  Alberta.  Very  similar  installation  to  5E  and  5J  above.  I  saw  this  one  at  the  airport  right  next  to  the  Mackenzie  Highway  as  I  was  traveling 
southward,  and  turned  off  the  highway  into  the  airport  to  take  this  photo  in  the  rain.  I  didn't  know  what  this  beacon  was  until  I  checked  my  Sony  portable.  Seemed  a 
weak  signal  even  close.  S.  McGreevy,  June  1996,  driving  southward  during  my  Solar-Minimum  Natural  VLF  Radio  recording  expedition  (featured  recordings  are  on 
my  2000  album:  'Auroral  Chorus  II').  (Initially,  I  thought  this  beacon  was  306  kHz  via  my  ICF-7600D  as  I  had  no  beacon  listing  of  it  with  me  on  the  trip.).  Heard 
since  in  Calif,  by  myself  and  others.

N5  224,  Rocky  Mountain  House,  Alberta.  Gail  and  I  drove  right  to  the  RMH  airport  looking  for  411  RM  (which  was  apparantly  off  the  air)  and  saw  this  little  beacon 
similar  to  all  the  other  small,  number-letter  beacon  installations.  I  had  to  check  the  radio  to  ID  it.  S.  McGreevy,  September  1993. 



(former  -  possibly  off-air  early  2018?)  239  OJ,  High  level,  Alberta.  This 
photo  was  taken  while  (90  km/h)  in-motion  southbound  on  the  Mackenzie  Highway  returning  from  the  Northwest  Teritories.  I  had  previously  spied  this  beacon  while 
driving  northward  to  the  NWT,  so  I  was  prepared  to  take  this  quick  (tilted)  shot  as  I  passed  by  it  again.  The  beacon  antenna  is  the  taller  mast  on  the  right  (telephone 
tower  is  the  left  one).  I  wish  I  had  taken  the  time  to  visit  this  site.  Weak  to  occasionally  fair  2-hop  signal  in  the  S.F.  Bay  Area  and  eastern  California,  it  is  a  quite- 
strong  1-hop  signal  (400  Hz  USB  ident  modulation)  in  southern  (Lake view)  Oregon  where  I  also  resided  and  monitored  it  (on  239.4  kHz  narrowband  CW/SSB 
mode)  for  good  northward  conditions.  S.  McGreevy,  June  1996.  OJ_239.jpg,  31,810  bytes. 


I  (former)  320  YQF,  Red  Deer,  Alberta.  This  strong,  high-power  NDB  uses  a  tall  self- 
supporting  mast  similar  to  many  U.S.  NDB's  (namely,  the  powerful  LOM/  formerly-TWEB  beacons).  Similar  antenna  mast  to  239  OJ  -  Alberta  and  320  HTN 
Montana  (see  HTN  below).  Gail  and  I  drove  many  miles  out  of  our  way  to  find  this  beacon,  but  could  not  get  closeer  than  this  somewhat  distant  shot.  Strong  signal 
throughout  western  North  America  with  400  Hz  USB  ident  modulation  pitch  (monitor  320.4  kHz  in  narrowband  in  CW/SSB  mode)  S.  McGreevy,  September  1993.

airport,  Alberta.  Taken  on  04  July  2001 ,  this  pretty  beacon  is  located  at  the  Pincher  Creek  airport.  I  drove  right  by  9Y  on  my  way  into  Pincher  Creek  in  order  to  get 
my  van's  oil-seal  fixed  there.  This  beacon  employs  the  uppermost  of  three  or  four  guy  wires  as  its  capacitance  umbrella,  as  do  many  Canadian  NDB's.  It  can  be  heard 
on  its  400  Hz  USB  ident  at  311 .4  kHz  between  the  US  DGPS  beacon  data  streams.  Sometimes  HY  Hay  River  NWT  accompanies  it  in  good  conditions.  Last  logged 
in  the  desert  of  Calif.  Christmas  morning  2005 .  S  .P.  McGreevy

540  CBK  Watrous,  Saskatchewan  (CBC-1).  Returning  southward  from  northern  Saskatchewan  after  my  VLF  Recording  Expedition,  and  on  my  way  toward  Waterton 
Park,  Alberta,  I  van-camped  10  miles  from  CBK.  The  next  morning  03  July  2001 , 1  stopped  by  this  great  AM/MW  radio  station  to  take  some  more  pictures, 
augmenting  my  photo  collection  of  CBK  from  September  1993.  540  CBK  has  a  gorgeous-looking  white  and  blue  painted  building  to  the  east  of  Watrous;  their 
formerly-used  open-feed  has  been  replaced  in-usage  with  the  thick,  black  coaxial  hard-line  cable;  and  CBK  has  the  largest  groundwave  coverage  of  any  North 
American  AM-BCB  station  (the  second  largest  is  550  KFYR  Bismark,  North  Dakota  with  5  kW)  -  on  a  good  car  radio,  the  daytime  groundwave  from  540  CBK  is 
clearly  listenable  from  the  foothills  of  the  Rockies  in  Alberta  well  southward  into  the  Great  Plains  of  central  South  Dakota  and  northward  up  to  the  NWT  border  from 
experiences  via  eight  road  trips.  Nighttime  reception  can  be  clear  even  in  Hawaii,  if  western  Samoa  or  XEWA  San  Luis  Potosi,  SLP,  Mexico  (etc.),  are  not 
interfering.  During  my  travels  in  Sask.  I  noticed  quite  a  number  of  residents  tuning  into  CBK  all  over  the  Province  -  CBK's  great  coverage  is  important  to  the 
Canadian  Broadcasting  Corporation  (CBC).  (Local  ground-conductivity  at  Watrous/CBK  exceeds  30  mmhos!  Contrast  that  with  0.3  mmhos  ground-conductivity 
calculated  in  the  Hilo,  Hawaii  [lava-geology]  region  from  the  1060  KAHU  signal  measurements  made  in  Sept.  1986  -  see  1060  KAHU  further  below  toward  the  page

scan  of  photo  taken  back  in  June  1985,  this  beacon,  then  on  a  weaker  382  kHz  frequency,  had  a  whimsical-looking  (to  us)  "inverted  coathangar"  antenna  not  seen 
before,  and  had  TWEB  (Transcribed  weather  broadcasts).  Sometime  in  the  mid  1990's,  MOG  moved  up  to  404  kHz  and  has  a  much  bigger  signal  (one  of  California's 
biggest  signals  now)due  to  tall  vertical  and  top.  cap.  hat  like  the  newer  305  ONO  Oregon  installation  (see  further  below  for  those  installations)  or  the  power  was 
increased  dramatically.  Mount  Shasta  makes  for  a  gorgeous  background!  S.  McGreevy,  June  1985.  382mog.jpg,  34,784  bytes.

(Former)  274  CQI  -  Council,  Idaho.  This  beacon  was  notorious  in  the  early  to  mid  1980's  when  it  had  severe  'negative  keying'  on  its  carrier  signal  (its  carrier  dropped 
substantially  when  the  ident  tone  was  keying)  leading  to  many  reports  of  an  unID  "IAEIK"  beacon,  and  CQI  also  radiated  a  well-heard  negatively-keyed  7th- 
harmonic  in  the  160-meter  amateur-radio  band  on  ~1918  kHz!  In  March  1988,1  deviated  160  miles  from  my  planned  route  in  order  to  see  this  notorious  beacon, 
which  by  then  was  behaving  almost  normally.  CQI  then  had  an  older  flat-top  wire  antenna  supported  by  wooden  poles.  During  1997  -  1999,  it's  ident  and  carrier  had 
not  been  detected  in  California,  and  I  think  it  went  off  the  air  back  then,  as  so  many  NDBs  are  today.  Photo  taken  March  1988  by  S.  McGreevy.  CQI274.jpg,  18,250

Guard  run  LORAN-C  radionavigation  station  a  visit.  We  were  told  to  leave  at  once  by  a  very  impolite  USCG  man,  surprisingly  so  very  unlike  our  Omega  visit  in 
North  Dakota  in  Sept.  1993  which  was  way-more  friendly.  Before  we  asked  to  visit  and  were  turned  away,  I  took  this  photo  of  the  base  of  the  huge  (700  foot- tall) 
antenna  mast,  with  three  of  its  top-capacitance-hat  (umbrella)  guywires  visible  behing  the  mast.  S.  McGreevy,  8/93.  loranc.jpg,  47,388  bytes

with  a  wire  skirt  -  a  hitherto  unseen  antenna  type  by  me,  but  one  that  I  am  aware  of  that  is  replacing  the  wire  antenna  installations.  30- watt  (listed)  ONO  gets  out  very 
well,  often  mixing  with  RO  Roswell,  New  Mexico  -  once  the  two  beacons  are  surrounded/buried  by  the  slow-speed  digital  data  sounds  of  the  DGPS  system,  as  both 
aeronautical  beacons  reside  in  the  marine  sub-band  of  285-325  kHz.  Happily  in  early  2018  305  ONO  and  RO  (Roswell,  NM)  mix  together  as  always  in  the  clear  now 
that  all  but  the  USCG  DGPS  beacons  have  left-air.  I  am  not  sure  if  ONO's  signal  level  changed  when  the  antenna  replacement  was  made  in  the  early  90s  -  it  was  a 
good  signal  back  in  1988  and  earlier,  too.  (February  2019:  Still  on-air  and  now  in  the  clear  again  now  that  the  305  kHz  Bakersfield  DGPS  station  is  off-air).  (This 
antenna  would  make  a  fine  LowFER  beacon  installation!).  S.  McGreevy,  9/93.

Burns,  Oregon  earlier  that  week  that  the  old  396  BNO  (off-air  now,  replaced  by  a  VOR)  beacon  transmitter  was  now  in  use  at  PLV!  (Sheldon  Remington  and  I  had

frequency  but  happily  still  transmitting.  PNA  was  always  one  of  those  beacons  I  wanted  to  visit  someday,  and  so  Gail  and  I  on  our  big  road  tour  of  September  1993 
detoured  a  bit  off  the  more  direct  highway  to  Jackson  Hole  and  Yellowstone  Nat.  Park  to  visit  PNA.  PNA  was  right  at  the  airport  in  an  adjacent  field.  The  beacon 
used  a  steel  lattice  mast,  guyed,  but  with  the  top  third  of  the  three  guy  cables  acting  as  a  top  capacitance  hat/umbrella.  PNW  was  new  variant  of  an  NDB  antenna

so  close  -  almost  as  weak  as  some  of  the  large  Canadian  NDB's  500  miles  away!  So  we  rolled  southward  toward  the  airport  hoping  to  spot  the  beacon,  and  here  it 
was.  It  is  a  rare  catch  in  California  (as  it  radiates  poorly).  One  end  of  its  two-wire  flat-top  antenna  is  supported  by  the  airport  light-beacon  platform.  S.  McGreevy,

The  former  379  SF  was  a  (literally)  bayside  beacon  right  south  of  the  western  on-ramp  to  the  San  Mateo  Bridge.  SF,  back  in  July  1987  when  this  photo  was  taken, 
and  it  employed  a  three- wire  flat- top  antenna.  It  was  an  location  inner- marker  for  the  approach  runways  to  SFO.  There  was  also  a  75 -MHz  marker  installation  and 
dipole  antenna  along  with  the  SF  beacon.  This  photo  was  taken  right  before  I  dropped  Sheldon  Remington  (ex.  NI6E/  now  KH6SR)  off  at  the  airport  (SFO)  the  day 
he  was  moving  to  Hawaii.  S.  McGreevy,  8/86.

-  333  STI  Mountain  Home,  Idaho.  Back  in  late  May  1984  when  this  (Kodak  110-film!)  picture  was  taken  with  a  poor-quality  110-type  camera,  STI  used  a  large  two- 
wire  flat- top  wire  supported  by  two  wooden  poles  painted  red  and  white  (very  similar  to  374  BKU  Baker  Montana  above  and  many  older  NDBs  you  see  pictured 
herein).  The  antenna  look  a  bit  dilapidated  when  Sheldon  and  I  visited  STI,  and  one  of  the  two  vertical  wire  feeds  to  the  flat-top  section  of  the  wire  antenna  was 
broken.  STI  still  is  on  the  air  but  with  a  somewhat  reduced  signal  since  the  early-mid  1980's,  and  I  presume  the  antenna  has  ben  replaced/updated.  S.  McGreevy,  5/84.

Fascinating  note  from  Mark  (AF6IM)  about  navigation  using  these  former  MARINE  NDBs: 

Stephen, 

I  really  like  your  natural  radio  website  a  lot.  You  might  want  to  include  a  link  to  my  website  (link  at  top  of  page)  which  has  first  hand  information  on  using  NDBs  in 
California  for  commercial  fishboat  navigation: 

https://sites.google.com/site/boeing377/using-military-surplus-radio-gear-on-commercial-fishing-boats 

There  was  an  extra  feature  on  the  Pt.  Bonita  NDB  (and  perhaps  others)  (the  former  296  "B"  Point  Bonita  Lighthouse  beacon  in  Marin  County  -  SpM)  that  allowed 
you  to  compute  range  in  fog.  All  you  needed  was  a  stopwatch  and  a  DF.  The  beacon  was  synched  with  the  foghorn.  You'd  use  a  stop  watch  to  measure  the  delay 
between  arrival  of  the  beacon  tone  and  the  foghorn  and  a  simple  speed  of  sound  calc  gave  you  range.  I  think  I  was  perhaps  the  only  person  who  actually  used  this  in 
the  60s,  but  it  was  quite  accurate  and  gave  me  position  info  at  a  critical  point,  entrance  to  S.F.  I  learned  about  it  in  some  obscure  pub  like  the  Coast  Pilot.  It  wasnt 
very  obvious  from  reading  the  nav  charts. 

I  was  sure  sad  to  see  the  low  power  USCG  local  harbor  NBBs  disappear.  I  used  them  at  Bodega  Bay  and  Santa  Cruz.  Super  useful  for  harbor  entrance  nav  before 
GPS .  They  worked  GREAT. 

Excerpt  from  my  website:  Manual  RDFs  were  really  hard  to  use  accurately  on  a  boat  that  was  often  yawing  pitching  and  rolling.  I  longed  for  an  ADF  (such  as  the 
Bendix  555  or  Jeppeson  units),  and  an  abundance  of  cheap  surplus  ARN  7  gear  allowed  me  to  get  one  dirt  cheap.  I  liked  ADF  navigation  and  used  it  to  full 
advantage.  There  was  an  AM  broadcast  station  in  Ft  Bragg  CA  (KDAC  1230  with  1  kW  -  SpM)  with  a  tower  sited  right  on  the  coast  that  gave  a  very  sharp-null 
which  enabled  me  to  always  find  the  Noyo  River  entrance  buoy  even  in  pea  soup  fog.  I'd  start  in  slightly  deeper  water  to  avoid  trouble,  find  the  correct  DF  bearing 
that  you'd  see  from  the  buoy  and  then  ride  the  bearing  into  the  charted  depth  that  the  buoy  was  anchored  in.  Bingo  every  single  time  even  in  nearly  zero  visibility.

The  loop  compensator  allowed  you  to  zero  out  nearly  all  bearing  distortion  from  the  boats  extensive  metal  commercial  fishing  rigging.  It  took  some  work  to  calibrate 
it  properly  but  when  set  up  right  it  worked  like  a  charm.  It  was  a  brilliant  design  using  a  circular  spring  steel  strip  cam  that  you  could  vary  the  shape  of  with 
circumferentially  spaced  adjustment  screws.  The  cam  follower  drove  the  loop  selsyn  and  gave  you  corrected  bearings  on  the  I  82  indicator.

sunny  spring  day  in  mid-March  1985.  We  had  heard  an  unID  beacon  on  212  kHz  sending  "TST"  for  months  prior  to  the  trip,  and  long-distance  loop  bearings  (from 
North  S.F.  Bay  Area)  pointed  toward  Oroville,  but  also  toward  a  few  other  small  airports  in  the  northern  Sacramento  valley  (colusa,  etc.),  and  so  we  took  a  trip  to  find 
TST.  After  a  day  of  enjoying  the  beautiful  scenery  and  spring  greenery  along  the  way,  we  located  TST  at  the  Oroville  airport.  Close-in  DFing  was  accomplished 
using  only  the  loopsticks  of  two  Sony  ICF-7600D  portable  receivers.  Later  that  day,  TST  went  off  the  air  (we  did  meet  airport  personnel  inquiring  about  this  beacon 
so  they  must  have  not  known  it  was  going  and  switched  it  off!).  It  later  returned  to  the  air  for  a  few  years  as  ident  OVE.  Photos  by  S.  McGreevy  March  1985.

201  IP  -  Mobile,  Arizona  -  26  Sept.  2006  -  Kirk  W. 


201  IP  Mobile,  Arizona  Good  friend  Kirk  W.  DFed  this  beacon  site  on  26  September  2006.  IP  is  located  about  7  miles  NW  of  Mobile,  Arizona,  and  is  solar-powered. 
193K  nice-resolution  photo.  Photo  by  Kirk  W. 


Kirk  writes  on  25  March  2008: 1  have  some  good  news  regarding  IP  on  201  kHz.  Frank  informed  me  that  this  beacon  is  now  back  on  the  ai  (ongoing  as  of  January 
2018  monitoring  -  SpM. 

It  had  been  off  the  air  for  several  weeks  but  I  checked  last  week  and  it  was  back  in  service.  Not  only  that,  it  now  appears  to  be  on  the  air  24  hours  daily.  Formerly,  it 
had  turned  off  at  1900  MST  every  evening  and  remained  silent  all  night  until  0600  MST  the  following  day. 

I  wonder  if  this  had  been  to  conserve  power,  as  IP  receives  its  only  power  from  a  bank  of  large  solar  panels.  (I  know  some  other  beacons  that  are  that  way,  too!)  I 
observed  no  above-ground  power  lines  feeding  the  beacon  in  its  desolate  location  in  the  Rainbow  Valley,  sandwiched  between  the  Maricopa  and  Estrella  Mountains 
in  a  sparse  Sonoran  Desert  landscape.  Now  the  beacon  IP  operates  continuously. 

This  shouldn't  create  a  power  shortage,  as  this  is  the  sunniest  time  of  the  year  in  southern  Arizona  and  there  will  now  be  more  daylight  than  nighttime  hours  for  the 
next  six  months.  Of  course,  there  may  be  unrelated  technical  reasons  for  the  beacon  having  been  QRT  for  a  few  weeks  and  changing  its  schedule.  This  is  good  news 
for  you,  as  it  gives  you  a  better  opportunity  to  hear  IP  during  nighttime  propagation  conditions. 

The  best  time  for  you  (SpM)  to  listen  for  it  would  most  likely  be  just  before  sunrise,  when  noise  from  thunderstorms  in  the  east  has  faded  down  but  nighttime 
conditions  are  still  in  existence  farther  west.

RYN  Ryan/Tucson,  Arizona  (Ant.  wires  not  visible  in  this  pic,  alas!  SpM)  Kirk  Writes  in  March  2008:  The  non-directional  beacon  RYN  (338)  is  contained  entirely 
inside  the  airport  boundaries.  As  a  result,  access  is  blocked  by  a  barbed  wire  fence  and  one  can  only  approach  the  beacon  within  100  yards.  RYN  is  actually  triple- 
protected  by  the  barbed  wire  fence  surrounding  the  air  field,  by  a  second  wire  fence  surrounding  the  entire  beacon's  electronics  and  antenna  structure,  and  by  a  third, 
small  wire  fence  surrounding  the  antenna  house  and  vertical  wire  that  reaches  up  to  the  top  hat. 

Prior  to  seeing  RYN  for  the  first  time,  I  was  actually  expecting  a  more  substantial  antenna  for  a  high-power  beacon  in  its  special  400- watt  class.  More  specifically,  I 
thought  I  might  find  a  red  and  white  vertical  tower  of  several  hundred  feet  (such  as  254  SPK;  320  HTN;  368  SX;  etc.  -  SpM).  Instead,  I  (Kirk  W.)  found  a  very 
typical  aeronautical  NDB  installation  consisting  of  a  vertical  wire  suspended  from  a  two-conductor  top  hat  strung  between  two  wooden  poles  (rather  hard  to  see  in 
Kirk's  photo,  though). 

It  was  almost  anticlimactic.  Of  course,  it  makes  sense  to  keep  any  structures  at  an  airport  as  low  as  possible. 

The  two  poles  are  perhaps  50  feet  in  height  and  the  top  hat  consists  of  two  horizontal  wires,  one  above  the  other.  The  two  horizontal  top  hat  wires  are  parallel  in  the 
vertical,  not  horizontal  plane  (similar  to  201  IP-AZ).  Very  high  voltage  insulators  are  used  to  attach  the  top  hat  wires  to  the  support  poles.  A  small  white  cubical 
structure  lies  beneath  the  center  of  the  top  hat  and  the  vertical  wire  appears  to  originate  from  it. 

Another,  larger  white  cubical  fiberglass-like  structure  lies  100  feet  away  near  a  VHF  antenna  structure.  I  wonder  if  the  smaller  structure  contains  just  the  tuning 
network  and  the  larger  structure  contains  the  beacon  electronics  and  its  power  supply.  The  larger  cubical,  boxlike  structure  was  very  reminiscent  of  the  structure  that 
exists  at  IP,  6  miles  northwest  of  Mobile,  AZ.  (IP  has  been  off  the  air  since  approximately  Wednesday,  February  6th,  2008.  -  back  on  -  see  above  -  SpM)  RYN's 
antenna  and  top  hat  are  basically  identical  in  size  and  form  to  that  used  by  IP. 

SpM  writes:  L**338  RYN  once  battled  it  out  at  night  throught  the  desert  southwest  with  PBT  Proberta/Red  Bluff,  California  to  the  point  both  must  have  cause  co¬ 
channel  QRM  if  either  beacon  were  employed  at  night  for  longer-distance  DFing  (audio  file  of  PBT  and  RYN  on  337.0  kHz  a  few  nights  ago  around  19  March  '08), 
which  does  employ  a  tall  vertical  mast  antenna-I  visited  PBT  in  June  1985  - 1  can't  find  the  slide  however...  and  NOTE:  PBT  (formerly  with  TWEB)  left  the  air 
around  December  2012.  SpM

Ground  conductivity  in  the  region  was  measured  via  field-strength  curves  at  (only  because  of  poor  ground-conductivity  lava 
terrain/geology)  =  ~0.3  mmhos!  -  SpM.  Additionally,  KAHU  employed  only  a  1/5  wave  tall  mast  due  to  close  proximity  to  Hilo
